Door leaf guidance in perfection
Copied a thousand times - but still unequalled. The door leaf is not wound-up on a shaft but kept space-saving in a certain distance in the patented EFAFLEX spiral. This functional principle guarantees you quite a number of unique advantages: only this unique design combines hightest opening speed, long service life and efficiency in such a perfect manner. Thanks to the spiral, the doors move quietly and wear-free - and look as good as new for many years.
